Our Manufacturing Process: From Sponge to Finished Bar

To ensure the internal integrity of our titanium, we follow a strict multi-step process:

Triple Vacuum Melting (VAR): Ensures high chemical homogeneity and removes gaseous impurities.

Precision Forging/Rolling: Refines the grain structure for superior mechanical properties.

Vacuum Heat Treatment: Stress relieving or annealing in controlled environments to prevent oxidation.

Finishing & Inspection: Centerless grinding followed by NDT testing to guarantee material integrity.

Quality Control & Testing Excellence

Chemical Analysis: Spectral analysis to verify alloy composition.

Mechanical Testing: Tensile, yield, and elongation testing.

Non-Destructive Testing (NDT): 100% Ultrasonic Testing (UT) to ASTM trim levels, and Eddy Current testing.

Microstructure Inspection: Verification of grain size and phase distribution (crucial for Grade 5 aerospace applications).

Third-Party Inspection: We welcome SGS, BV, and TUV inspections before dispatch.

Packaging & Global Logistics

Secure Packaging

Individual plastic wrapping + reinforced plywood cases (ISPM 15 compliant).

Anti-Damage Design

Soft padding between layers to prevent surface scratches during transit.

Fast Dispatch

50+ tons of Gr2/Gr5 bars in stock for immediate worldwide shipping.

FAQ

Q: Is your titanium 100% traceable?

A: Yes. Every bar is linked to a specific heat number. We provide a full MTC (EN 10204 3.1) covering chemical and mechanical properties with every shipment.

Q: Can you meet h7 or h8 diameter tolerances?

A: Absolutely. Our in-house centerless grinding ensures precision tolerances up to h7 and surface roughness Ra < 0.4μm, perfect for high-speed CNC machining.

Q: Do you accept small trial orders for R&D?

A: Yes, we support flexible MOQs. We understand that aerospace and medical projects often start with small-batch material validation.

Q: How do you ensure no internal defects?

A: Every bar undergoes 100% Ultrasonic Testing (UT). We guarantee zero internal cracks, voids, or inclusions according to AMS 2631 standards.

Q: What is your standard export packaging?

A: We use individual plastic wrapping inside reinforced, ISPM 15 compliant plywood crates to ensure zero surface scratches during international transit.

Q: Do you provide samples for material verification?

A: Yes, we provide small samples for chemical and mechanical testing. For medical grades, we can provide samples from specific batches to ensure biocompatibility compliance.

Q: Can your titanium bars meet AMS 4928 standards for aerospace?

A: Absolutely. Our Grade 5 (Ti-6Al-4V) bars are manufactured strictly according to AMS 4928 specifications, including macrostructure and microstructure requirements.

Q: What is your standard lead time for international orders?

A: For stocked items, we ship within 3-5 days. For custom production runs, the typical lead time is 15-30 days depending on the volume and specifications.
